CIRP Annals-Manufacturing Technology《国际生产工程科学院年鉴-制造技术》（半年刊）. CIRP, The International Academy for Production Engineering, was founded in 1951 to promote, by scientific research, the development of all aspects of manufacturing technology covering the optimization, control and management of processes, machines and systems.

Circulation Research《循环研究》（半月刊）. Circulation Research is an official journal of the American Heart Association and is the official journal of the Council on Basic Cardiovascular Sciences of the American Heart Association. Circulation Research is published as a print and online journal with 24 issues per year.

Circulation: Heart Failure《循环：心力衰竭》（月刊）. Circulation: Heart Failure considers for publication content related to heart failure, mechanical circulatory support and heart transplant science and medicine, including studies conducted in humans or analyses of human data, as well as preclinical studies that have direct clinical correlation or relevance.

Circulation: Genomic and Precision Medicine《循环：基因组与精准医学》（双月刊）. Circulation: Genomic and Precision Medicine considers all types of original research articles, including studies conducted in human subjects, laboratory animals, in vitro, and in silico.

Circulation: Population Health and Outcomes《循环：人群健康与疗效》（月刊）. In January 2026, Circulation: Cardiovascular Quality and Outcomes changed its name to Circulation: Population Health and Outcomes. The goal of Circulation: Population Health and Outcomes is to catalyze groundbreaking research focused on cardiovascular health and disease outcomes, with an emphasis on: Epidemiology and population health, especially as these relate to cardiometabolic risk factors in population and community settings; The influence of care delivery on cardiovascular outcomes within health systems and communities; Cardiovascular disease prevention inclusive of randomized clinical trials, community intervention trials and implementation science studies.

Circulation: Cardiovascular Interventions《循环：心血管介入诊疗》（月刊）. Circulation: Cardiovascular Interventions, an American Heart Association journal, focuses on interventional techniques pertaining to coronary artery disease, structural heart disease, and vascular disease, with priority placed on original research and on randomized trials and large registry studies. In addition, pharmacological, diagnostic, and pathophysiological aspects of interventional cardiology are given special attention in this online-only journal.

Circulation: Cardiovascular Imaging《循环-心血管影像》（月刊）. Circulation: Cardiovascular Imaging, an American Heart Association journal, presents high-quality, patientcentric articles focusing on observational studies, clinical trials, and advances in applied (translational) research featuring innovative, multimodality approaches to diagnosis and risk stratification of cardiovascular disease. Modalities covered in this monthly journal include echocardiography, cardiac computed tomography, cardiac magnetic resonance imaging and spectroscopy, magnetic resonance angiography, cardiac positron emission tomography, noninvasive assessment of vascular and endothelial function, radionuclide imaging, molecular imaging, and others.

Circulation: Arrhythmia and Electrophysiology《循环：心律失常与电生理学》（月刊）. Circulation: Arrhythmia and Electrophysiology will include articles related to research in and the practice of clinical cardiac electrophysiology and the diagnosis and management of cardiac arrhythmias, including observational studies, clinical trials, epidemiology, and advances in applied (translational) research.

Circuit World《电路世界》（季刊）. Circuit World publishes multidisciplinary research on a range of topics relating to all types of electronics circuit including; design, application, manufacturing, assembly, safety and special sections on new technology trends and application areas.

Circuits, Systems, and Signal Processing《电路、系统和信号处理》（月刊）. Rapid developments in the analog and digital processing of signals for communication, control, and computer systems have made the theory of electrical circuits and signal processing a burgeoning area of research and design. The aim of Circuits, Systems, and Signal Processing (CSSP) is to help meet the needs of outlets for significant research papers and state-of-the-art review articles in the area.
